71 * The __CONCAT macro is used to concatenate parts of symbol names, e.g.
72 * with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
73 * The __CONCAT macro is a bit tricky -- make sure you don't put spaces
74 * in between its arguments. __CONCAT can also concatenate double-quoted
75 * strings produced by the __STRING macro, but this only works with ANSI C.

108 * GCC has extensions for declaring functions as `pure' (always returns
109 * the same value given the same inputs, i.e., has no external state and
110 * no side effects) and `dead' (nonreturning). These mainly affect
111 * optimization and warnings. Unfortunately, GCC complains if these are
112 * used under strict ANSI mode (`gcc -ansi -pedantic'), hence we need to
113 * define them only if compiling without this.
